【摘要】：在電子商務(wù)時(shí)代，，很多企業(yè)的需求具有脈沖的特點(diǎn)：每當(dāng)進(jìn)行打折、團(tuán)購等促銷活動(dòng)或者某些節(jié)日時(shí)，市場需求在短時(shí)間內(nèi)激增，使得訂單量出現(xiàn)較大的波動(dòng)，本文將這種短時(shí)間內(nèi)需求激增的現(xiàn)象稱為脈沖效應(yīng)，與此對(duì)應(yīng)的供應(yīng)鏈體系稱為脈沖供應(yīng)鏈。目前，電商環(huán)境下的供應(yīng)鏈企業(yè)在滿足脈沖需求方面能力不足，引發(fā)了一系列問題，其庫存策略亟待深入研究。 本文在前人對(duì)供應(yīng)鏈庫存控制以及庫存系統(tǒng)仿真等內(nèi)容的研究基礎(chǔ)上，從供應(yīng)鏈系統(tǒng)的整體利益出發(fā)，以供應(yīng)鏈利潤最大化為目標(biāo)，結(jié)合系統(tǒng)動(dòng)力學(xué)理論對(duì)單一制造商、單一零售商構(gòu)成的兩級(jí)供應(yīng)鏈進(jìn)行了深入分析，并以Vensim仿真軟件為建模平臺(tái)構(gòu)建了系統(tǒng)動(dòng)力學(xué)模型。在模型中，本文將終端市場需求分別設(shè)定為單次脈沖和多次脈沖，主要以制造商和零售商的提前期為控制變量進(jìn)行了模型仿真，對(duì)比分析了不同提前期策略下脈沖供應(yīng)鏈利潤、庫存等因素的變化情況，得出的主要結(jié)論如下：在單次脈沖和多次脈沖供應(yīng)鏈中，實(shí)施可控零售商提前期策略時(shí)的利潤高于正常提前期和隨機(jī)提前期，且隨著提前期的壓縮，利潤呈現(xiàn)先增后減的變化趨勢；當(dāng)制造商和零售商提前期均可控時(shí)，整條供應(yīng)鏈的利潤高于正常提前期和隨機(jī)提前期時(shí)的利潤；在供應(yīng)鏈中，制造商的利潤空間會(huì)影響整條供應(yīng)鏈的收益。
[Abstract]:In the era of electronic commerce, the demand of many enterprises has the characteristics of pulse: whenever the sale, group purchase and other promotional activities or certain festivals, market demand surge in a short period of time, making the volume of orders fluctuate greatly. In this paper, the phenomenon of demand surge in a short period of time is called pulse effect, and the corresponding supply chain system is called pulse supply chain. At present, supply chain enterprises in e-commerce environment have insufficient ability to meet impulse demand, which leads to a series of problems, and its inventory strategy needs to be studied in depth. On the basis of previous researches on inventory control and inventory system simulation of supply chain, this paper aims at maximizing the profit of supply chain and combines the theory of system dynamics to single manufacturer, starting from the overall benefit of supply chain system. The two-level supply chain composed of a single retailer is deeply analyzed, and the system dynamics model is constructed on the platform of Vensim simulation software. In the model, the terminal market demand is set as single pulse and multiple pulse respectively. The model simulation is mainly based on the lead time of manufacturer and retailer, and the profit of pulse supply chain under different lead-time strategy is compared and analyzed. The main conclusions are as follows: in the single-pulse and multi-pulse supply chain, the profit of the controllable retailer's lead-time strategy is higher than that of the normal and random lead-time, and with the compression of the lead-time, the profit of the controlled retailer is higher than that of the normal and random lead-time. When the manufacturer and retailer can control the lead time, the profit of the whole supply chain is higher than that of the normal lead time and random lead time; in the supply chain, The profit margin of the manufacturer will affect the profit of the whole supply chain.
